Hi Carrie,
I am waiting to pick up my BC pup on 29th November and can't wait.
We found the breeder on both epupz and pets4homes.
It is a farm but we have been up twice to see our pup and it is a lovely place.
The breeder has lots of BC's and we were able to see them all. (Adults not puppies)
I don't know which area you live in but both of these sites cover the UK.
Beware of scammers, my daughter in law nearly fell foul of one and was about to pay £160 without even seeing the pup apart from a pic!!! I had to stop her.
I also have a Border Collie X and she is 14 years old, she has been the best dog and most obedient I have had.
Good luck, hope you find what you are looking for.................be sure to let us know!!
P.S I have just started a blog about my dogs if anyone is interested lol.
Only one post on there but will build up when I can.
